摘要： This invention provides a method for power-efficient transmission supporting integrated service over WLAN. The said invention combines the polling-based and the contention-based mechanisms, named on-demand polling (ODP). In the ODP scheme, a voice station is in the polling list when it is in the active mode. During the idle mode, it is configured to operate in the sleep mode for saving power. Also, it adopts the contention-based mechanism to join the list again while returning from the idle mode. On the other hand, the data station adopts the contention-based mechanism to transmit its packets over WLAN. In addition, to achieve service differentiation, the said invention also employs a prioritized access probability for voice over data services. Simulation results show that the said invention can reduce the power consumption for voice stations and enhance the throughput for data stations.
